8 Claims. (Cl. 164-28) My invention relates to the cutting of paper stock into seals or stickers for packages, wrappers and the like, and more particularly to means for cutting the units on a quantity basis, and one object of the invention is to provide a machine for the above purpose which operates on a high speed rotary principle.

A further object is to devise a machine of the above character which cuts a series of longitudinal units from which the seals are made, such units being grouped in a manner to leave no paper waste between them.

Another object is to design the novel machine with a cutting unit which operates under spring pressure and insures the full application of the cutting blades to the paper stock.

An important object is to construct the machine along lines of compactness and simplicity.

With the above objects in View and any others which may suggest themselves from the description to follow, a better understanding of the invention may be had by reference to the accompanying drawing, in which- Fig. 1 is a vertical section of the machine;

Fig. 2 is an elevation as seen from the righthand side of Fig. 1; and

Fig. 3 is a plan view of a fragment of the paper stock after it has been cut and formed in part into stickers.

Referring specifically to the drawing, in denotes a pair of side walls forming the frame of the machine. The walls ID are spaced at the top by a shaft l l whose ends l2 are tightly driven or otherwise rigidly secured to the walls; and the walls journal front and rear shafts l3 and M in the lower portion of the frame.

The rear shaft I4 is designed to receive motion from a suitable power source (not shown), and carries a hard-surfaced roller l5. The shaft I3 is made with a series of longitudinal splines l6, and carries a set of circular cutter discs Il formed with serpentine peripheral blades I8. Each disc H has a hub I9; and the latter fits the splines IS with a. small amount of radial play.

Generally, the spacing of the shafts l3 and I4 is such that the cutter blades l8 meet the surface of the roller and the shafts carry meshing gears and 2| to render the roller and cutter blades movable in unison, as indicated by arrows in Fig. 1. Thus, when the paper web 22 is fed over the roller IE it descends in the zone of contact between the blades and the surface of the roller, causing the web to be cut into ribbon units 23 having wavy edges 24. With the undulations of the blades regular, the formations of the units 56 23 intermesh, as seen in Fig. 3, leaving no stock waste between the units. when the units are separated, as shown in the right-hand portion of the same figure, each may be cut into lengths as indicated at 25 to form the stickers 26-.

Means are provided for utilizing the radial play in the cutter discs H to apply their blades l8 with spring pressure to the paper web 22 and thus take up possible failure of blade contact caused by depressions or wear in the blades. Thus, the shaft ll journals a series of pendent arms 21 at points above the respective cutter discs II. The arms are divided with sections 28 straddling the related cutter discs and journaling their hubs I9; and a series of collars 29 space the arms 21 along the shaft II.

Fig. 1 shows that the frame of the machine has a fixed frontal cross-bar 30; and that setscrews 3| are directed through the latter to urge a spring 32 against each arm 21, the set-screws receiving locking nuts 33. The same figure shows that the spring pressure has urged the disc hubs [9 toward the left, so that the full and continuous cutting contact of the blades I8 is thus insured.

It will now be evident that the novel machine secures the continuous and geared application of the cutter blades to the moving paper web; that the design of the cutters is such as to form a series of ribbon units which leaves no paper waste between them; that the blade pressure is independent of the rotary running gear and secures the thorough application of the cutter blades to the work; that the blades are yieldable to pass irregularities or abnormalities in the zone of blade contact; and that the machine is built compactly and with the fewest number of parts consistent with efl'icient operation.

While I have described the invention along specific lines, various minor changes or refinements may be made therein without departing from its principle, and I desire to consider such changes and refinements as coming within the scope and spirit of the appended claims.

I claim:

1. Means for cuttinga web into units comprising a rotatable roller receiving the web, a series of discs arranged in parallelism to the roller, means to jointly rotate the discs in a direction to advance the web through a contacting zone between them and the roller, and blades carried peripherally by said discs to cut the web in said contacting zone, a shaft carrying the series of discs and having a series of longitudinal splines, means in the discs to engage the splines and allow the discs 9. small amount of radial play,

- 3 v and other means utilizing such play to urge said blades into engagement with the web.

2. Means for cutting a web into units comprising a rotatable roller receiving the web, a series of discs arranged in parallelism to the roller, means to jointly rotate the discs in a direction to advance the web through a contacting zone between them and the roller, and blades carried peripherally by said discs to cut the web in said contacting zone, a shaft carrying the series of discs and having a series of longitudinal splines, coacting splines in the discs and allowing the same a small amount of radial play, and other means utilizing such play to urge said blades into engagement with the web.

3. Means for cutting a web into units comprising a rotatable roller receiving the web, a series of discs arranged in parallelism to the roller, means to jointly rotate the discs in a direction to advance the web through a contacting zone between them and the roller, and blades carried peripherally by said discs to out the web in said contacting zone, a shaft carrying the series of discs, means to rotatably join the discs to the shaft with a small amount of radial play, a carrier pivoting each disc for movement toward and away from the web, and means to urge the carrier toward the web to keep said blades in engagement therewith.

4. Means for cutting a web into units comprising a rotatable roller receiving the web, a series of discs arranged in parallelism, to the roller, means to jointly rotate the discs in a direction to advance the web through a contacting zone between them and the roller, and blades carried peripherally by said discs to cut the web in said contacting zone, a shaft carrying the series of discs, means to rotatably join the discs to the shaft with a small amount of radial play, a carrier pivoting each disc for movement toward and away from the web, and yieldable means to urge the carrier toward the web to keep said blades in engagement therewith.
